项目中评价的模型和方法研究摘要：本文在对传统项目评价的概念进行扩充之后，提出了项目前评价、项目中评价及项目后评价的概念，并重点对项目中评价的相关评价模型进行了探讨，提出了项目中评价的二维结构模型、聚类评价模型、递进评价模型及项目中评价的 DEA 评价方法。关键词：项目评价，项目中评价，项目管理Research on the Models of Project Interim EvaluationBai Sijun (Management School of Northwestern Polytechnical University)Abstract: As an important part of project management theory, Project Evaluation (PE) has basically formed a theory and method system. Many project life cycles are similar from the start to the end, including project determination; and then undergoing the project definition, manning, resources allocation, work planning, executing operating and so on. There is a series of evaluation problems in each period. Obviously, these evaluation problems have their related evaluation theory and method system. The set of the theory and method will constitute the perfect system of PE. In this paper, we extend the traditional concept and connotation of PE and present the concept of PE corresponding the whole project life cycle, and divide it into Project Ex Ante Evaluation (PAE), Project Interim Evaluation (PIE) and Project Ex Post Evaluation (PPE), and mainly analyze the models of PIE. This paper presents the model of two-dimensions framework, the model of clustering evaluation, the model of step-advance evaluation and the method of data envelopment analysis.Keywords: Project Evaluation, Project Interim Evaluation, Project Management1.引言项目评价作为项目管理的主要理论之一，已得到较为全面的发展，并形成了较为完善的评价理论与评价方法体系，特别是项目前期论证和项目后期评价方面。然而人们对项目最为重要的执行阶段的相关评价问题却很少进行探讨，本文基于此对传统的项目评价概念（在可行性研究的基础上从宏观和...
